SPlNNlNG-RING HOLDER.

SPECIFICATION forming part of Letters Patent No. 628,825, dated July 11,1899.

Application filed February 20,1899. Serial No. 706,205. (No model.)

To all whom it may concern:

Be it known that I, EARL P. MASON, of Newport, county of Newport, Stateof Rhode Island, have invented an Improvement in Spinning-Ring Holders,of which the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

This invention has for its object the production of a novel andconvenient holder for retaining spinning-rings in place on the ringrailand to facilitate their application to and their removal from the same.

At present the ordinary form of ring-holder is held in place on the railbytwo screws with overlapping heads, the bodies of the screws enteringradial notches or slots in the base or body portion of the holder, andit is necessary to take out one of the screws in order to apply orremove the holder.

By virtue of the construction of my novel ring-holder it is onlynecessary to slightly loosen the screws, whereupon the holder may beswung aside to be completely disengaged from one screw and thereaftertipped slightly and withdrawn from the other one. This readiness ofremoval or application is a great convenience, as holders are changedfrequently when spinning with different sizes of 0 rings.

Figure 1 is a top or plan view of a ringholder mounted on the ring-rail,partly shown, the ring being shown in place on the holder; and Fig. 2 isa side elevation of the holder dis- 3 5 engaged from one retaining-screwand tipped in readiness to be withdrawn from the other.

Referring to Fig. l, the usual ring-rail R is shown as provided with theusual retainingscrews S S for the holder, said screws having overlappingheads to bear upon the base or body h of the ring-holder.

I have herein shown the holder as made of sheet metal, the annular bodyIt having the usual upturned lugs or clips h struck up from 5 its innercircumference to engage the foot of the ring R and provided with atravelerclearer 7L Instead of providing the body with oppo'sitely-located radial slots extended inward from its periphery I makethe opening to one slot, as 72 radial and to the other slot 72substantially tangential, the inner end of the slot h being nearlydiametrically opposite the slot lbs.

The periphery of the holder-body is concaved or recessed at 71?, Fig. 1,adjacent and outside of the mouth of the tangential slot 7%, for apurpose to be described.

Supposing the holder to be in place on the rail R, as in full lines,Fig. 1, with the screwshanks in the bottoms of the slots h 77.4, if itis desired to remove the holder the screwsare loosened and the holder isswung bodily to the right into dotted-line position, Fig. l, on thescrew S as a center until the recess 72, is opposite the head of thescrew S, the tangential position of the slot 71. permitting suchswinging movement of the holder. The holder is then lifted at one side,as shown in Fig. 2, to clear the head of screw S, the recess h providingthe necessary clearance and obviating undue swinging movement, and thenthe holder is withdrawn from beneath the head of screw S by movement inthe direction of the arrow 5, Fig. 2. hen the holder is to be replaced,the operation is reversed, the part of the holder having the radialnotch 71. being slid under the head of screw S, so that the shank of thelatter enters the slot and the holder is dropped onto the rail past thehead of screw S by means of the clearance-recess 77.

Swinging movement of the holder to theleft, Fig. 1, from dotted to fullline position locks the screw Sin the tangential slot 7r and the twoscrews are tightened.

My invention is not restricted to the precise construction andarrangement shown and described, for, so far as I am aware, it isbroadly new to provide a ring-holder which maybe removed from thering-rail or applied 0 thereto without removing one or bothretaining-screws.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- y 1. As a new article of manufacture, aspinning-ring holder having a tangential lockingslot,toreoeive the shankof the holding means.

2. As a new article of manufacture, a spinning-ring holder having twoopen screw-re- Ioo ceiving slots, one of said slots being substantiallytangential to the inner circumference of the holder to receive the shankof the holding means.

3. As a new article of manufacture, an annular, sheet-metal holder forspinning-rings, provided with upturned ring-engaging lugs and having atangential locking-slot in its bodyportion to receive the shank of theholding means.

4. As a new article of manufacture, a spinning-ring holder having itsbody provided with a substantially tangential, open-ended locking-slot,the periphery of the body having a recess therein adjacent and outsidethe open end of the slot.

5. As a new article of manufacture, a sheetmetal holder forspinning-rings, having a radial slot in its body portion withoutwardlydivergent sides, and a cooperating tangential EARL P. MASON.
